Hebei Julite Sorting Technology Co., Ltd. offers its Destoner Screen for Sale, a precision machine engineered to remove stones, heavy soil clumps, and dense foreign materials from grain and seed streams. Designed for continuous operation in grain elevators, seed processing plants, and feed mills, this destoner screen combines vibratory motion with calibrated airflow to achieve high-purity output.
Working Principle and Workflow
Material is delivered onto a vibrating screen deck that features adjustable air injection ports beneath a perforated plate or screen cloth. As the deck oscillates, heavier stones and dense particles settle closer to the deck surface while lighter grains or seeds ride higher on the deck. Simultaneously, an upward airflow counteracts the deck’s vibration, further stratifying the mixture. At the end of the deck, diverter plates channel the heavy fraction—stones and dense impurities—to one outlet, while the cleaned grain exits the opposite side. Operators can fine-tune deck angle, vibration frequency, and airflow volume to match the specific gravity differences of local grain varieties and prevailing impurity profiles.
Key Features
Adjustable Deck and Airflow: Deck inclination and oscillation speed are set via a PLC/HMI interface, while a variable-frequency blower controls airflow. This flexibility allows configuration for wheat, barley, rice, corn, oilseeds, and pulses.
Robust Construction: The destoner screen frame and deck supports are fabricated from heavy-gauge steel, resisting structural fatigue under continuous vibration. Screen panels and air-permeable deck plates use stainless steel, ensuring corrosion resistance and sanitary operation.
Ease of Maintenance: Quick-release screen panels and slide-out deck inserts simplify cleaning and deck replacement. Centralized lubrication points ensure bearings and vibrating motors receive regular service without disassembly.
Scalable Capacities: Models range from pilot units able to process 1 t/h to industrial systems handling over 20 t/h, supporting operations of any scale.
Applications and Benefits
By removing dense contaminants early in the processing line, the Destoner Screen for Sale protects downstream equipment—such as grinders, mills, and optical sorters—from damage and wear. Eliminating stones and heavy debris also reduces maintenance needs and prolongs service life across the entire production system. The cleaner output supports higher-quality flour, feed pellets, or seed lots, meeting strict quality standards for food safety and agronomic use.
Hebei Julite Sorting Technology Co., Ltd. provides full support for each destoner installation, including site layout consultation, equipment commissioning, operator training, and scheduled preventive-maintenance plans to help clients sustain reliable, high-performance separation.
